The casting device comprises a liquid collecting cover 1, a sealing gasket 2, a casting pipe 3 and a hanging frame 4, and is shown by referring to FIG. 1, wherein the liquid collecting cover 1 is communicated with a storage bin, and a casting nozzle is arranged at the top of the liquid collecting cover 1; the sealing gasket 2 is arranged at the top of the liquid collecting cover 1, and a sealing port is arranged on the sealing gasket 2; the mould 5 is installed in stores pylon 4, and the one end of casting tube 3 communicates in mould 5, and the other end passes seal port and casting gate and stretches into in the liquid collecting cover 1, and the bottom of stores pylon 4 is equipped with the bearing surface. When casting, the hanging frame 4 can move downwards to enable the bearing surface to be in contact with the upper surface of the sealing gasket 2, and the sealing gasket 2 is compressed under the action of the weight of the hanging frame 4 and the weight of the mould 5, so that the sealing between the bearing surface and the sealing gasket 2 is realized, and the leakage is avoided in the casting process. After casting is completed, the hanger 4 moves upward to separate the bearing surface from the gasket 2. Because mould 5 and stores pylon 4 are pressed on sealed pad 2 through the bearing surface, compress sealed pad 2 through the dead weight, realized the sealed of mould 5 and the butt joint department of collecting cover 1, simple structure, reliability are high, can not need to adopt the manual work to prick to tie casting pipe 3, therefore can realize man-machine isolation, improve the security and the efficiency of production.

Specifically, referring to fig. 2, the hanger 4 may include a frame body 41, a bearing portion 42, and a leg 43. The mold 5 is fixed to the frame body 41, and the bearing portion 42 is provided at the bottom of the frame body 41 and protrudes from the lower surface of the frame body 41, and the lower surface of the bearing portion 42 is a bearing surface. The support legs 43 are also arranged at the bottom of the frame body 41, specifically, the support legs 43 can be arranged at two sides of the frame body 41, and the height of the support legs 43 can be larger than the thickness of the bearing part 42, namely, the bearing surface is positioned between the bottom surface of the support legs 43 and the frame body 41 in the vertical direction, and the hanger 4 can be supported and placed through the support legs 43 in non-working time without damaging the bearing surface.

In an exemplary embodiment of the present disclosure, the diameter of the sealing port on the gasket 2 is greater than the diameter of the casting nozzle. Referring to fig. 3, when the hanger 4 drives the die 5 and the casting tube 3 to move downwards, the casting tube 3 is facilitated to pass through the sealing port, so that quick butt joint with the liquid collecting cover 1 is realized. The gasket 2 may be an annular gasket and the bearing portion 42 may be cylindrical, and in some exemplary embodiments the outer diameter of the gasket 2 may be equal to the outer diameter of the bearing surface, i.e., the orthographic projection of the upper surface of the gasket 2 onto the bearing surface coincides with the boundary of the bearing surface such that the lower surface of the bearing surface is fully conformed to the upper surface of the gasket 2. In other exemplary embodiments, the outer diameter of the gasket 2 may also be slightly smaller than the outer diameter of the bearing surface, i.e. the orthographic projection of the upper surface of the gasket 2 on the bearing surface is within the boundary of the bearing surface to ensure that the bearing surface is sufficiently compressed against the gasket 2.
